so i wanted to transplant a 320i (4cyl) from e21 into my e30.. after some searching for a while i found one.. $450.. i went to look at it and it looked beautifal.. the head was.. well it looked brand new, and the guy claimed that he had rebuilt it for his friend who had since moved away and nolonger wanted the engine.. me not knowing alot about engines.. what to ask.. or what to look for.. just bought it.. he said it had new pistons rings clutch.. bla bla..
anyway.. i took it down to my BMW mechanic (indipendant) and got him to pull it apart check it out.. i was wanting some work done to the head and a few other little things.. he pulled the head cover off and it all looked great.. pulled the sump off.... well first thing he noticed was all these tiny little shiny copper(i think it was copper.?) at the bottom of the sump.. he proceded to pull the bearing covers off (im typing this from memory.. so exuse the lack of knowlege on my part..) and the first two were new.. all good so far.. then on the third one.. the bearing was blue..
turns out the bearing was screwed and over used and heated and had completly worn out.. it had scratches and dints (where bits of metal had been caught in it and it had scraped.. and he'd just put a differant older ring(?) on there so it would turn.. and it kept driving and bent the crank.. now the crank doesnt turn at all.. so im up for a nother bottom end.. but the head im keeping.. if i deside to go ahead with this transpalnt.. if not ill go the m/s50
